BMW Z3, Z4, and M3 make the good list, X5 V8 makes the bad list...

Small cars

Honda Civic

The Honda Civic is reliable, economical, and fun to drive. It grew with the 2001 redesign, and 2003 saw the introduction of the Hybrid model. The 2006 redesign included standard antilock brakes (ABS), curtain air bags, and a better ride. An alternative with more cargo room is the Scion xB, which also has standard electronic stability control.
Other good choices:

* Toyota Echo
* Scion xB
* Toyota Corolla
* Toyota Matrix
* Pontiac Vibe
* Mazda3
* Mazda Protege
* Subaru Impreza

Family cars

Honda Accord

The Accord has been a very reliable used-car choice. The 2003 redesign made it quieter and more agile, and it received standard ABS. Standard ESC arrived on V6 models in 2006 and on all models with the 2008 redesign. The Ford Fusion and Mercury Milan have very good reliability, tested well, and are very affordable.
Other good choices:

* Toyota Prius
* Ford Fusion
* Mercury Milan
* Toyota Camry (except '08 V6)
* Subaru Outback (6-cyl.)
* Nissan Altima

Upscale cars

Lexus ES

The ES has been very reliable through its many generations. This quiet and comfortable sedan was redesigned in 1997 and 2002 but got a stronger, more fuel-efficient engine in 2004. ESC became standard in 2007. The Acura TL and TSX are sportier alternatives.
Other good choices:

* Lexus IS
* Toyota Avalon
* Acura TSX
* Lincoln MKZ, Zephyr (FWD)
* Infiniti G20
* Acura TL
* Infiniti I30, I35
* Infiniti G35 (sedan)
* Volvo S60
* Buick Lucerne (V8 )
* Nissan Maxima

Luxury cars

Infiniti M35

Since 2003 the M has been a reliable model, but the 2006 redesign made it comfortable when cruising the highway and on twisty roads. The V6 is strong, and the interior is well finished. The Lexus LS is a more luxurious choice.

Other good choices

* Lexus LS
* Lexus GS (6-cyl., RWD)
* Acura RL

Sports and sporty cars

Mazda Miata

The slick shifter, nimble handling, and good performance make the affordable and reliable Miata fun to drive. ABS became standard with the 2006 redesign; look for the optional ABS on older models. A practical alternative is the Subaru WRX, which gives great performance along with standard AWD and four doors.
Other good choices

* Lexus SC
* Honda S2000
* Toyota Camry Solara
* Acura RSX
* Toyota Celica
* Scion tC
* BMW Z3, Z4
* Acura Integra
* Porsche Boxster
* BMW M3
* Subaru Impreza WRX/STi
* Ford Mustang (V6)
* Nissan 350Z


Toyota Sienna

Toyota's first-generation Sienna is refined, but the third-row accommodations are snug. In 2003 a redesigned Sienna went on sale. It is roomier and more powerful, and it's available with AWD. Reliability has been very good overall. The Honda Odyssey isn't as plush but has better handling.
Another good choice:

* Honda Odyssey

Small SUVs

Toyota RAV4

Introduced in 1996, the RAV4 was the first car-based SUV. It was agile and comfortable but small and underpowered. The 2001 redesign brought more power and a roomier interior. ESC arrived in 2004. For 2006 Toyota added an available third row. Throughout its life the RAV4 has had stellar reliability.
Other good choices:

* Honda CR-V
* Subaru Forester
* Mitsubishi Outlander

Midsized and large SUVs

Honda Pilot

Introduced in 2003, the Pilot is roomier than its MDX sibling and less expensive. It's roomy and refined, delivers good fuel economy, and has flexible seating for eight. Crash-test results are impressive, and reliability has been excellent. The Toyota Highlander is a good choice with an optional third-row seat.
Other good choices:

* Toyota Highlander
* Lexus RX
* Toyota Land Cruiser
* Toyota 4Runner
* Infiniti FX35
* Acura MDX
* Infiniti QX4
* Lexus GX
* Hyundai Santa Fe
* Subaru Tribeca
* Nissan Xterra ('05-08 )
* Toyota Sequoia

Pickup trucks

Honda Ridgeline

Honda's pickup rides and handles like a sedan but delivers the utility of a truck. The V6 engine is smooth and responsive, and the cabin is nicely detailed and easy to access. The in-bed, weather-tight, and lockable trunk is a plus. Opt for the Tundra if you need more towing or off-roading capability.
Other good choices:

* Toyota Tacoma ('05-08 )
* Toyota Tundra
* Subaru Baja
* Nissan Frontier ('05-08 )
